BUTTON-ATTACHING MACHINE.

SPEGIFIOATION forming part of Letters Patent No. 507,083, dated October17, 1893.

Applleationfiled July 9,1891.

To all whom it may concern.-

Be it known that I, ISAAC H. SISSON, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements inButton-Attaching Machines; and I do hereby declare the following to be afull, clear,.and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

In a companion application for Letters Patent I have described andclaimed certain novel improvements in button-setting ma chines of thevertical or standard type. My present invention also has relation tomachines of this class.

My invention consists, essentially, of a stationary anvil orsetting-die, an adjustably mounted yielding button-and-fastener magazineand holder, a plunger-carrying head having the magazine and holdermounted therein, the plunger or driver being pivoted to the head, andmeans for reciprocating the head 7 ing in its extreme up-stroke.

in a vertical direction.

In the accompanying two sheets of drawings, Figure 1, Sheet 1, is a sideelevation in partial section of the upper portion of my improvedbutton-setting machine, buttons and fasteners being omitted and the headbe- Fig. 2 is a similar view of the parts, the head being in its extremelowest position. Fig. 3 is a plan View of the head. Fig. 4 is ahorizontal sectional view, taken on line w ocof Fig. 1. Fig. 5 is anenlarged side View, in partial section, of the lower portion of thebutton-and-fastener magazine, holder and plunger. Fig. 6 is a similarsectional view, the plunger being in the act of attaching a button tothe fabric. Fig. 7 is a vertical transverse sectional view, takenthrough the lower portion of the tube v and holder, on line 00 0c ofFig. 8. Fig. 8 is a cross sectional view, taken on line ,2 z of Fig. 6.Fig. 9 is a front elevation of the magazine and its holder. Fig. 10 isan inverted end view of the holder, enlarged.

fabric or other suitable material. Fig. 12, Sheet 2, is a frontelevation, the magazine and holder being omitted. Fig. 13 is a side viewof the same, in partial longitudinal central section, and Figs. 14, 15and 16 are views of the lower portion of the plunger or driver. Myinvention resides in the upper or head portion of the machine. Machinesof this class are usually arranged to be operated by a treadle-lever,its connection passing upwardly through a hollow standard; the latterbeing secured at its upper end to a frame or spider, which in turn issecured to the base or table of the machine. This feature, however,being common, I have deemed it unnecessary to represent said parts morein detail. In the drawings 11. indicates the top of the base or table tothe under side of which the frame or spider u is secured.

10 indicates the upper portion of a hollow spindle screwed into theframe u. See

To the top of the table it is secured an upright frame a provided with abent arm or anvil a and a base a the frame a is bored out centrally tofreely receive a head 0. The head itself is bored to, receive a rod m,the latter being enlarged at its lower end m and having a pull-rod ortreadle-connection r attached thereto. The upper end of the rod m isscrew-threaded and provided with a nut m the lower portion of the headcis recessed or bored and is provided with a spring m. By means of thisarrangement the spring automatically returns the head and its attachedparts to the normal or upper position (see Fig. 13) upon removingpressure from the rod or connection 'r. The head is prevented from axialmovement by means of the slot a into which the point of the screw a isfitted. The head 0 is further provided with the lateral extension or arm0'. This arm is cut away or recessed along its under side to receive theplunger or driver I). The driver being pivoted at 10 is really a leverhaving downwardly bent ends b, 12 The arm 0' is further recessed at apoint between the centers of the fulcrum p and the rod mto receive thespring m arranged to engage the inner end or arm of the driver. The sideof the upper portion of the frame on adjacent to the anvil is slottedlongitudinally at s to permit the end I) of the driverto freely-move upand down therein. A narrow bar or tie extends across the face of theupper portion of the slot; the lower end of the arm I) is enlarged andin engagement with the rear face of the tie when the head is in itsextreme vertical position, see Figs. 1 and 13, the springm maintainingthe parts in contact. The free end of the other portion, b of the driveris provided with a vertical slot n to freely receive the eyeshanks ofbuttons. This portion of the driver is further provided with the frontprojection 77. arranged to enter the space formed between i the twolowest fasteners maintained in the magazine and holder, the under side01 of the driver being arranged to engage the crown or arch w of thetwo-prong metallic fastener 10 so that upon carrying the driverdownwardly to its limit it forces the prongs of the fastener through thefabric and clinches them thereunder by reason of their engagement withthe die (1 retained in the anvil a.

- The opposite outer sides of the arm 0' of the head 0 are groovedlongitudinally, as at e, toreceive corresponding ribs or flanges e ofthe magazine-holder e. Adjacent to these side grooves the arm is drilledto receive a screw f and spring f the upper end of the holder beingtapped out to receive the adjusting nut f the latterin turn being tappedto receive the screw f By this it will be seen that the holder e isguided vertically, and at the same time being both yielding andadjustable.

To the front of the holder is secured a central longitudinally arrangedguard g. This guard serves to prevent the button heads contained in theslotted magazine if from overlapping each other. When guards are notemployed it occasionally happens that the buttons stick or becomecramped in the tube thereby preventing them from dropping regularly. Thelower portion of the holder 2 is cut away at the rear, as at h, topermit the entrance of the front arm b of the driver, seej Figs. 7,8,10, &c.

The magazine or tube t is provided with a; longitudinal front slot 15'communicating with the slot 15 formed in the lower portion of the Asdrawn the tube is made of sheet; metal-bent to shape and arranged toreceive; two-prong metallic fasteners w and the con-j nected eye-shanksw of button w, as clearly holder e.

represented. The upper and lower portions of the holder are adapted toreceive the tube, 15, a pin t passing transversely through the partsserving to hold the tube in position. The back of the tube at its lowerend con-, tiguous to the pin-hole is provided with thef bent spring-stop1" arranged to prevent the buttons and fasteners from falling out. Upon.

inserting the pin 1', however, the latter presses the stop rearwardly,see Figs. 5, 6, &c., thereby permitting the column of buttons and fas-,teners to freely pass downwardly to the setting mechanism, or untilarrested by the spring-stop 5 located in the lower end of the so aossfastener grooves g of theholder, see Figs. 5 and 7.

Assuming the head a and its several connected parts to be in the extremevertical normal position, represented in Figs. 1, 5 and 7, the operationof the machine in attaching buttons, would be substantially as follows:-

Now upon forcing the spring-resisted head a downwardly theenlarged endZ) of the driver passes the tie 7c, the spring m immediately vibratingthe driver 1) upon its pivot, thereby causing the upper portion l of thedriver to engage the corresponding surface of the arm a; such movementat the same time causing the lower end of the arm b to vibrate towardthe front of the holder and between the eyes of the two lower buttons.At the same time such downward movement will have brought the lower endof the spring resisted holder e into engagement with the fabric fresting upon the die d, when now a further movement of the head bringsthe under side 02 of the driver into engagementwith the arch of thelowest fastener; the final movement causing the driver to force theprongs of thefastener past'the yielding stop .3 and through the fabric fand clinching them thereunder against the face of the die; the positionof the parts then being substantially as indicated in Figs. 2 and 6.During the latter part of the operation just described the holder e andits magazine remain practically stationary while the head 0 is'stilldescending, thereby compressing the holder-spring f. It will'be seenalso that by reason of the rigid engagement of the contiguous surfaces Zof the arm 0 and the driver'the upward thrust orpressure due toclinching of the prongs is borne directly by thehead itself, the twoparts'for the time being practically as one, I would further state thatas the driver forces the bottom fastener downwardly a secondfastenerfollows in unison until arrested by the stop s, the arrangement of "thefasteners being such that they practically rest one upon the other, seeFigs. 5,6 and 7. After the button has been thus attached, uponwithdrawing pressure from the pull-rod r, the spring 'm, carries thehead, &c., upwardly and rearwardly again to their limit, as inFig. 1;the spring f at the same time carrying the holder and magazinedownwardly to their limit. During such upward movement of thehead thearm I) willby reason of its engagement with the tick cause the driver toresume its former or'substantially horizontal position, as representedin Fig. 1, thus completingthe operation.

I claim as my invention- 1. In a button setting machine, an anvil,'amovable head havinga yielding holder adapted to receive and guidea'fastener and its connected button,and slotted inits rear wall .topermit entrance of a driver,combined with a staple driver pivotedto themovable head eating movement toward and from the slotted holder so as toenter said holder from the rear and engage the crown of the fastenerheld therein, substantially as described.

2. In a button-setting machine, avertically movable head having adriverb pivoted thereto, a spring arranged to vibrate the driveroutwardly or away from the axis of the head so as to engage a button andfastener, and at the same time having the upper frontportion of thedriver bearing against the head, and a stationary bar arranged to engagewith and return the spring-resisted driver to its nor: mal positionduring the upward movement of the head, substantially as described.

3. In a button-setting machine, the combination with a stationary anvilor setting die and a driver-carrying head adapted to verti cal movement,the driver carried by said head
